I think. Well, I hope.
The whitelist at
http://dumps.wikimedia.org/other/pagecounts-all-sites/README.txt
claims that
meta.mediawiki.org is whitelisted. As is
usability.mediawiki.org. As is...you get the picture ;)
Unless I've had a stroke and am hallucinating the *.mediawiki.org, we
mean wikimedia. At least it validates the people who grumble the two
names are too similar? ;)
Have fun,
